Study Notes

Programming Languages

Procedural programming language: Example is C
Object-oriented programming language: Example is Java
Interpreted programming language: Example is Python
Compiled programming language: Example is C++

Hardware

Hardware refers to the physical components of a computer
Input device: Example is a keyboard
Correct definition of hardware: Physical components of a computer that can be seen

Programming Concepts

High-level programming languages: Purpose is to make programming easier and more efficient
Example of high-level programming language: Python
Compiler: Purpose is to translate high-level language into machine code
Object-oriented programming language: Example is Python
Interpreted programming language: Example is Python
Python syntax is case-sensitive
int(round(time.time() * 1000)) returns the current time in milliseconds since midnight, January 1, 1970

Python Code

x=1; x=2*x+1; print(x) returns 3
x=1; x = x + 2.5; print(x) returns 3.5
x, y = 1, 2; x, y = y, x; print(x, y) returns 2 1
Correct input for x, y = eval(input("Enter two numbers: ")) is a string of two numbers separated by a comma
import math; r = float(input("Enter radius: ")); if r > 0: print(math.pi * r ** 2) displays the area of a circle if the radius is positive
temperature = 50; if temperature >= 100: print('too hot'); elif temperature < 100: print('just right'); else: print('too cold') returns 'just right'
i = 1; while i < 10: print(i, end=' '); i = i + 2; if i == 5: i = 9 returns 1 3 9
i = 1; while i <= 9: print(i, end=' '); i = i + 1; if i == 9: print('End') returns 1 2 3 4 5 6 7 8 9 End
String literal is enclosed in quotes
Valid identifier in Python: Example is myVariable
Correct comparison operator in Python: Example is ==
print("A", end = ' '); print("B", end = ' '); print("C", end = ' '); print("D", end = ' ') returns A B C D
